XLSFONTS 1 "Release 5" "X Version 11"

Xlsfonts
lists the fonts that match the given pattern.
The wildcard character "*" may be used to match any sequence of
characters (including none), and "?" to match any single character.
If no pattern is given, "*" is assumed.

The "*" and "?" characters must be quoted to prevent them from
being expanded by the shell.

This option indicates that xlsfonts should do an OpenFont (and
QueryFont, if appropriate) rather than a ListFonts. This is
useful if ListFonts or ListFontsWithInfo fail to list a known
font (as is the case with some scaled font systems).
